A newly formed hurricane rapidly gained force off Mexico's Pacific coast on Sunday and forecasters said it could reach Category 4 status before hitting land by midweek. A hurricane watch was posted for a stretch of shore between San Blas and Mazatlan.

Hurricane Willa was about 270 miles south-southwest of Cabo Corrientes Sunday morning with maximum sustained winds of 100 mph.

The U.S. National Hurricane Center said Willa could become a major hurricane by Monday morning and near the coast by Tuesday night. It said the storm could produce dangerous storm surge, while dumping 5 to 10 inches of rain across parts of western Jalisco, western Nayarit and southern Sinaloa states, with lesser amounts falling as it moves inland.

Meanwhile, Tropical Storm Vicente appeared to be a less potent threat further south. Forecasters said it was likely to remain just offshore or near Mexico's southern Pacific coast through Monday night and perhaps edge ashore on Tuesday.

It was located about 100 miles southeast of Puerto Angel with winds of 50 mph.

The Hurricane Center said it could produce 3 to 6 inches of rain near the coast.
